When the 200$ subscriptions launched almost everyone (including me) were skeptical and thought no one would pay so much, now I personally know more people than I can count who have them.
- I have both ChatGPT and Claude Max.
- I wonder if we will see an even higher tier introduced from OpenAI or Anthropic this year.
- I chose 400$ since it felt right.
